Homebrew 3-watt vacuum tube guitar amp built on a bread tin using tubes that were common with the table radios of the 50's and 60's. This amp uses an isolation transformer for safety. Due to specific configuration needs, this amp operates on 120v only.

They could be made available for sale.  I need to build a couple more.  I traded my MA1 bread pan amp for a sweet boutique CBG the other day.  I still have my bread pan AA4 amp.

Hey Jeff,

This version of my All-American Four was a gift to a good friend in the UK.  It is wired for 240v. 

The reason the MA1 cannot be used directly on 240 is due the need for a 60v transformer.  This trick was accomplished by wiring the primary of the MA1's transformer for 240v for use on 120v mains, giving the needed 60v at the secondary.
